How To Choose A Underground Water Leak Detector

The underground water leak detector is mainly used to detect the leakage of buried tap water pipelines, and the listening instrument to locate the leakage point can also be used to locate the leakage point of other liquids and gases. With pointer, cursor, audio, digital display methods. Small size, light weight, easy to carry, while choosing a groundwater leak detector requires special attention.

The underground water leak detector should choose high resolution. Simply put, it is the exact number of digits detected, such as 1Pa or 0.1pa. There are many resolution units, such as Pa, ml / min, etc. Choose according to your product testing requirements. Accuracy testing of groundwater leak detectors is required. The first meaning of precision is accuracy. For example, shooting can directly hit the bullseye. The second meaning is the allowable deviation range. The size of the bull's eye area is the same as hitting the bull's eye, and the accuracy of hitting a small area of the bull's eye is high.

Underground water leak detector require multiple repetitive tests. This is the most important index, which can reflect the comprehensive performance of the instrument. The so-called repeatability refers to the consistency of the data displayed by the instrument under the same ambient temperature and the same test pressure. The choice of groundwater leak detector depends on the strength of the manufacturer, and the overall strength of the business can be comprehensively judged from the aspects of the quality of sales staff, market share, and customer strength.

Do You Know The Calibration Of The Gas Detector?

By placing the instrument in the corresponding test gas of known concentration and comparing the detection result of the gas detector with the gas concentration, the gas detector can be calibrated to understand the accuracy of the gas detector. For example, n-hexane burns and explodes when the VOL content is 1.1%. If a 10% alarm is set on the hexane detector, an alarm will be triggered when the hexane concentration reaches 0.1%. For catalytic combustion sensors, this concentration is very low. The alarm value of toxic gas is much lower than that of combustible gas. For chlorine, the threshold alarm value is only 0.5 ppm.


The difference between the measurement result of the recalibrated gas detector and the measured gas concentration is usually less than 10%, so the instrument can be used without calibration. For example, the ammonia gas detector detects 50 ppm standard ammonia gas. If the measurement result of the instrument is 46ppm, 46ppm is 50±10%X50, and the result is 45~55ppm, it can be considered that the detection accuracy of the ammonia detector can be certified without recalibration. I will. Similarly, if the detection result of this ammonia gas detector is 44ppm, it must be recalibrated before using this detector.

Advantages Of Pipe Inspection Crawler Camera Non-destructive Inspection

The urban underground pipeline network includes urban water supply, drainage, electricity supply, natural gas supply and communications. It is an important part of urban infrastructure. The underground pipeline network is the "ship" and "nerve" of the city, and also the lifeline of the city. With the rapid development of urban construction, China has increased the development and utilization of underground space in recent years. More and more underground pipe networks have been laid in cities. However, due to the large number of property units involved and the lack of unified standardized management, data in the underground pipeline network is inconsistent and the underground pipeline network is unknown. Because the underground pipe network is hidden, the actual location and depth of the pipe network cannot be determined. The underground pipeline network is sometimes damaged during construction. Construction management and old city reconstruction have brought hidden dangers.



If the pipeline is not tested, repaired and cleaned in time, it may cause accidents and cause unnecessary losses. However, the environment where the pipeline is located is usually not easy to reach directly or people are not allowed to enter directly, so it is difficult to detect and clean. Therefore, one of the most effective methods is to use pipe inspection crawler camera to realize online pipeline inspection, maintenance and cleaning.



The pipe inspection crawler camera consists of a controller, a crawler, a high-definition camera and a cable car. During operation, the controller is mainly controlled by the controller to control the crawler equipped with detection equipment to enter the detection pipeline. During the inspection process, the pipeline inspection crawler camera robot can transmit video images of the internal conditions of the pipeline in real time for professional maintenance personnel to analyze the internal failure of the pipeline.



Advantages of using robot nondestructive testing for underground pipeline inspection:



1. High security. Use the pipeline to check that the crawler camera robot enters the pipeline to find out the internal condition of the pipeline or eliminate the hidden danger of the pipeline. If it is manual operation, there are usually greater safety hazards, and the labor intensity is high, which is not conducive to the health of workers. The intelligent operation of the pipeline robot of Shandong China Coal Group can effectively improve the safety performance of the operation.



2. Save labor. The pipe inspection crawler camera is small in size and light in weight. It can be operated by one person. The controller can be installed on the vehicle, saving labor and space.



3. Improve efficiency and quality. Shandong China Coal Group's pipeline inspection crawler camera robot has intelligent operation and precise positioning, and can display date and time, crawler inclination (pipeline slope), air pressure, crawling distance (measurement line), laser measurement results, and azimuth angle (optional ). The display status of these information can be set through the function keys. Camera angle clock display (location of pipeline defect).



4. High protection level. The camera protection grade is IP68, which can be used at a water depth of 5 meters, and the crawler protection grade is IP68, which can be used at a water depth of 10 meters. It has air-tight protection, waterproof and anti-rust materials, so there is no need to worry about quality issues, because Shandong China Coal Group only Good pipeline inspection crawler camera robot.



5. High-precision cable reel, telescopic cables do not affect each other, and the length is optional. The pipeline inspection crawler camera robot is suitable for various pipelines with a diameter of 100mm-2000mm. It can not only improve the accuracy of operation, but also save labor and improve production efficiency. In addition, it is easy to identify the internal factors of the pipeline and maintain the pipeline in certain environments that are not suitable for manual operation. .



With the help of pipeline inspection crawler camera robots, faults and damages in the pipeline can be easily found, which not only saves manpower, but also reduces the amount of construction and greatly improves work efficiency. It will become the main trend of China's pipeline network inspection, and the application of pipeline inspection crawler camera robots in the national pipeline network census is also an inevitable choice.
